Abstract (en)
A recording and/or reproducing apparatus (1) for a magnetic tape cassette (67) has a back-tension arm (88) pivotably mounted on a mechanical chassis (2) of the apparatus (1) and an actuator mechanism (82) for releasing braking force applied on a pair of tape reel bases (10, 11) by a pair of braking arms (75, 76) while a magnetic tape (71) is run at a high-speed speed. The actuator mechanism (82) includes an axially sliding connector rod (84) engaging with a slider (93) through which said back-tension arm (88) is actuated according to movement of the connector rod (84), whereby the back-tension arm (88) may apply light friction to the take-up reel base (11) in a reverse running mode in which the magnetic tape (71) is fed from the take-up reel (11) to the supply reel (10) by rotation of a capstan (45) and pinch roller (49) at a relatively slow speed, to prevent slack in the tap (71) when it is started in the reverse running mode.
